Cosgrove, to which patent reference may be had for the description of parts not more fully set forth herein and embodies a frame 10, upper cement receptacle 12 and control handle 1 1 of the type shown in that patent.

To adapt the machine for coating opposite facesof work, such as the fastener strip 28 of the type used in overshoes or gaiters and shown in Fig. 7, opposed coating rolls. 20 and 26 are utilized. Accordingly, the machine has an upper arm 16 (Fig. 3) in which there is journaled a shaft 18 for the upper roll 20 and it also includes a pivoted lower.

arm 22 in which there is journaled a shaft 2a carrying the lower cement applying roll 26 which takes the place of the work-supporting driven feedroll of the patented machine. A cement receptacle 3O partially surrounds and supplies cement to the lower roll 26 and is secured by screws to the end of the arm 22. A sheet of packing material 32 is interposed between the edges of the cup-likereceptacle and the end of the arm '22 to make a tight joint and provision ismade for supplying cement to this receptacle from a tank 34: (Fig; 1) through a conduit 36 held by bolts 38 to a flange 40 (Fig. 2) on the lower receptacle '30. It will be understood that the supply tank 34 is of the barometric type and that when it is desired to remove the cement for the night or in order to clean the machine, a valve 42 in the conduit 36 may be opened to drain off the remaining cement.

i It will be noted from Fig. 4 that the upper cement roll 20 is substantially wider than the lower roll 26, although the inner lateral faces of the two rolls are in alinement. This leaves a substantial overhanging portion of the upper roll toward the end of the machine where the work is not supported by the lower roll and it is found that, lacking'support' at this point, the cement would be unevenly applied at the inner margin of the'upper stripe. Accordingly, there is provided a supporting arm having an inturned upper end 52 adapted to underlie and to support the work,

, holding it against a. portion of the upper roll 20. This arm'50 is pivotally mounted onthe end of the receptacle 30 by means of a screw stud 54 and has a limited swinging movement within a notch 56 (Fig. 2) provided inthe upper edge of the lower receptacle 30. A spring'58 secured to the lower end of the pivoted arm 50 (Figs. 1 and 3) tends to hold the upper end 52 of the arm directly beneath the upper roll but allows it to be displaced forwardly and downwardly by a thickened portion of the work as thelatter is fed in the direction indicated by the solid arrow in Fig. 1. I In order to assist in feeding the work to the machine alongthe desired path, there are 7 associated with the lower roll afwork table 6O anda work guide 62. 'lhework table 60 serves not only to support the work up to a point close to the bite of the rolls, but is also arranged to serve as a scraper to control the amount of cement delivered by the lower roll. To this end it rests upon an inclined surface 64: (Fig. 2) of the cement receptacle 30 which is substantially tangential to the surface of the lower roll. The forward edge of the table 60 is beveled and may be moved closer to or farther away from the periphery of the lower roll, acting as a scraper to remove surplus cement from the surface of that roll. For convenience of adjustment and in order to'hold the combined table and scraper 60 in adjusted position, it is provided with a depending flange 66 having an inclined slot parallel to the surface (i l of the recepcacl'c, through which slot passes a retaining screw 68. This flange rests against a boss 7 O which is machined to provide a smooth surface in a plane exactly normal to the axis of the roll so that in all of its adjusted'positions the table 60 will act uniformly across the whole width of the lower roll it scrapes off the surplus cement.

The work guide 62 is provided with a vertical surface 72 acting as an edge gage against which the edge of the work may be positioned as it is guided over the table 60, and fastened to this upright surface 7 2 is a holddown having an outwardly extending flan e 74 tendi'ng to prevent curling of the wor 7 Theforward corner of this flange is turned upwardly to facilitate entering the work in the machine. One'portion of the gage member 62 fits closely against the surface of the table 60 and'may be adjusted across this surface to meet the requirements of any particular piece of work which is presented to the machine. To this end the edge gage 62 has a depending slotted arm 76 through which passes a clamping screw 7 8 to holdit to the lower arm 22 of the cementing machine. It will-beunderstood that the arm 22 is pivoted in the machine and may be low ered when no work is passing through the machine, or may be raised as a piece of work is presented to the machine to bring the two rolls 20 and 26 into contact with the opposite sides of the work 28. The lower roll 26 is provided with lateral flanges to help in holding the cement on the surface of the roll and has a series of frusto-pyramidal studs arranged over its surface to help to carry a suihcient body of cement. The roll 26 is removably mounted on'the end of the shaft 24. In common with the machine disclosed in United States Letters Patent No. 1,380,360, referred to above, the upper roll 20 is detachably mounted on its shaft 18 and is held within a removable casing .80 provided with a supporting stud 82 which fits tightly within a socket provided in thefupper arm 16 of the machine and is clamped'in position by means of a clamping screw 84:. However, to

assist in removing the casing from the machine after the clamping screw has been loosened, there is herein provided an opening 86 in the arm 16 in which may be inserted a stud has been partly removed from its socket.

Looking toward the prevention of leakage of cement across the lateral faces of the roll 20, the casing is provided with side plates 90, 92 each of which is recessed to receive a felt insert 94 and these plates are pressed against the sides of the roll by means of a screw 96 threaded in the casing. In the herein described machine, the quantityof cement carried by the upper roll is determined by a horizontally arranged scraper 100 guided in a path parallel to and adjacent to the lower edges of the casing 80. Although it is pos sible to use a great variety of rolls in amachine of this type with satisfaction, it has been found that one particularly appropriate form is that illustrated in the drawings in which t 1e surface of the roll isprovided with a series of closely adjacent circumferential V-shaped grooves. By thus greatly increasing the peripheral surface, the quantity of cement carriedby the roll may be substantially increased without dripping. For the proper control of he quantity of cement carried out by this form of roll, the forward end 101 of the scraper 100 is similarly grooved to fit the grooved surface of the roll 20. In any event, the forward end of the scraper is ll-shaped, being ground away to provide a slot between forwardly extending side arms 102 which are arranged closely to these projecting arms 102.

engage the sides of the roll completely to clean cement from the lateral surfaces of the roll adjacent to the periphery. The side lates and 92 are notched at 104 to receive The notches 10 extendall the way through the side plates 90,

02 so that adjustment of the screw 96 will not cause the plates 90 and 92 to bind the scraper. ()n the other hand, these plates lit closely a ainst the top and bottom faces of the iper arms 102 and prevent leakage at this point. Adjustment of the position of the scraper to control the quantity of cement'delivered by the upper roll 20 is effected by means of an adjusting screw 106 threaded in the casing 80 and rotatably held in a slot of the upturned end 103 of the scraper 100. A stop screw 110 is mounted in this upturned end to limit the inward movement of the scraper so that it cannot be jammed against the surface of the roll to cause undue wear or breakage. V

Leakage of cement between the scraper and the casing 80 is also effectively prevented by providing the sides of a thickened portion 103 of the scraper with inwardly extending grooves 111 (Fig. 6) to receive tongues 112, 112 (Fig. 3) formed upon the inner faces of the casing. These tongues and grooves are each of rectangular shape so as to provide a plurality of angula rly related contacting faces in any leakage path between the receptacle and the outer air. lVithout being machined within such fine limits as to make the cost of the machine prohibitive, these" faces form an effective barrier to the leakage of cement. V

The piece of material from which the scraper 100 is formed may readily be ground away to provide a medial slot at its inner end between forwardly extending side arms 102, which slot will he of such dimensions that the side arms engage closely against the sides of the roll. The operation can be performed with considerable accuracy without involving any large cost. It will be seen therefore, that the described construction effectively prevents leakage not only through any joints between the scraper and the casing, but also between the sides of the roll and the forwardly extending arms of the scraper as well between the lea rage-preventing plates 90, 92 and the scraper arms 102.

In spite of all precautions, a small quantity of cement may find itsway on to the lateral surfaces of the roll 20 and in order to facilitate the return of this cement to the receptacle, the side plates 90, 92 are cut away as indicated by the inclined line 116 in Fig. 5 and by the inclined line 118 in Fig. 6 to provide a tapered passage through which the cement will be continually packed back into the receptacle as it is scraped from the lateral surfaces of the roll and brought to a point 120 (Fig. 6) adjacent to the upper rear side of the roll.

In the use of the machine, supposing that the receptacles 12 and 34 have been filled with cement, the operator will insert a piece of work (which may, of course, have more than the single'thickness illustrated) beneath the holddown T4- and against. the edge gage 72 and, starting the machine by the control handle 1 1, will raise the lower arm 22 by means of a treadle (not shown) connected to a treadle rod 122 (Fig. 1). A portion of the work opposed to the overhanging portion of the wider roll 20 will be supported by the yielding arm 52 which will hold this portion i of the work in sufficiently firm contact with the upper roll so as to insure a proper coating of cement. The control of the quantity of cement delivered by the lower roll 26 is effected by adjustment of the combined work table and scraper 60, and the control of the quantity of cement delivered by the upper roll 20 is effected by the adjustment of the scraper 100.
